T 0 all Whom it may concern:

Be it knownthat 1, LEONARD E. ALLYN, citizen of the United States, residing at West Mystic, in the county of New London and State of Connecticut. have invented certain new and useful Improvements in Fluid- Current Conveyors, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in iiuid pressure conveyers, one object of the invention being the provision of a novel arrangement of conveyor mechanism in which fluid, air or steam, under pressure is employed to discharge various granular materials, the same when used with compressed air being adapted for discharging grain cargoes and when used with steam to form an ejector for moving water or other fluid, while when used with water the same will discharge sand or other ballast at sea, or at any other point desired.

A further object of this invention is the provision of a simple construction which is readily assembled, easily taken down for repair, renewal or adjustment, and one which is exceedingly small and compact.

In the accompanying drawings:

Figure 1 is a side elevation partly in section, of the complete device, when material is fed through the hopper.

Figure 2 is a similar view showing the parts in the position they assume when material is acted upon by suction.

Figure 3 is a detail end view of the nozzle.

Figure 4 is a view taken at the opposite end thereof.

Figure 5 is a plan View of the hopper sk rigure 6 1s a plan view of the suction gasket.

Referring to the drawings, the numeral 10 designates the water supply pipe having the concentric nozzle 11, projecting concentrically through the nozzle block chambe l2 concentrically ot' the nozzle block 13, en'iptying into the n'iaiu ejector housing 1?. The steam supply pipe 11, having a hamlvalve 15 leads into the chamber 12, steam then passing through the converging removable tubular nozzles 16, into the main ejector housing 17. which as shown in Fig. 1, is provided with an opening 18 through which material from the hopper 19 is fed thereinto. Detachably connected in the smooth portion 20 of the ejector housing is the nozzle block 13', which as shown in Figures 3'and 4, is provided with the central opening 22 and the six outer openings Each nozzle 16 is constructed so as to have the restricted inlet portion 24 and as shown in cross section in F igurcs 1 and 2, flares upwardly in an opposite direction from an intermediate point. As shown in Figure 1, the motive iiuid when entering the ejector housing will assume the position of the arrows and cause the material entering the opening l8 to be directed into and through the discharge line This construction is used especially when it is desired to discharge grain. Where it is desired to discharge sand, or the like, the plate or sealing member 27 is placed as shown in Figure'2, while the circular closing member 28, as shown in Figures 1 and 6, is removed so that the suction pipe 29 will be connected directly and material may be sucked therefrom and delivered to the pipe A stuliing box 30, is provided at the inlet end of the nozzle block about the water nozzle 11.

The suction and discharge lines are to be made of standard piping while the rest of the machine is made of malleable or cast iron, except the nozzles, which are made or composition which will stand best under the circumstances. v I

From the foregoing description, it will be seen that with a device made according to this invention, the same can be used as a conveyer for grain, sand and also for water by the use of compressed air, water or steam, as the prime mover.

lVhat is claimed as new is:

1. In a device of this kind, the combination with a motive fluid conducting member, a valve for controlling the same, a chamber in communication therewith, a main ejector housing also in communication with i said chamber, a nozzle member at the junction between the two, a pipe line leading from the ejector housing chamber in an opposite direction to the nozzle, said ejector housing being provided with two oppositely disposed inlets, and means for closing one inlet at a time whereby any desired character of ma terial may be drawn into the housing for delivery into the pipe line.

2. In a device of this kind, the combination with a motive fluid conducting member,

a valve for controlling the same, a chamber in communication therewith, a main ejector housing also in communication with said chamber,-a nozzle member at the junction between the two, a pipe line leading from the ejector housing chamber in an opposite direction to the nozzle, said ejector housing being provided with two oppositely disposed inlets, and means for closing one inlet at a time whereby any desired character of material may be drawn into the housing for de livery into the pipe line, said nozzle member including an integral member having a central nozzle and a plurality of converging nozzles surrounding the same.

In testimony whereof I aflix my signature.

LEONARD E. ALLYN.
